Prevention of glyphosate resistant kochia scoparia in Western Canada

Kochia （Kochia scoparia）是加拿大南部大草原上的一种重要杂草，它已经对用于控制其的大多数常见除草剂具有抗性。Kochia目前在加拿大西部使用草甘膦进行控制，在所有作物中预先播种，并在抗草甘膦的油菜和甜菜中使用。在美国已经发现了抗草甘膦的kochia，这引起了人们对抗性kochia的关注，无论是在这里选择还是通过种子运输到加拿大西部引入。

Kochia (Kochia scoparia) is a significant weed of the southern Canadian Prairies, one that is already resistant to most common herbicides used for its control. Kochia is currently controlled in Western Canada using glyphosate, applied pre-seeding in all crops, and in-crop in glyphosate resistant canola and sugar beets. Glyphosate-resistant kochia has been identified in the US, raising concerns about resistant kochia, either by being selected here in or introduced by seed transported to western Canada.
